Overview
This is Melanotan II supplied as a ready-made solution rather than a lyophilized powder: 10 mg of peptide in 10 mL (1 mg/mL), filled into a metered spray bottle that delivers 100 mcg per actuation, about 100 actuations per bottle. The peptide is the same cyclic heptapeptide as the 10mg vial in this catalog. Supplied for laboratory research use only; not for human or veterinary use.
In experimental systems, Melanotan II is characterized as a non-selective agonist at melanocortin receptors (MC1R, MC3R, MC4R and MC5R). It is widely used as a reference ligand in receptor-binding and signal-transduction studies, in models of pigmentation and melanocyte biology, and in investigations of melanocortin-mediated pathways governing energy balance and appetite signaling. Its constrained cyclic scaffold also makes it a common tool compound in structure-activity and peptide-stability research.
